TMS570LS3137: Debugging using only FTDI mini module

FTDI Pins to TMS570LS3137 JTAG pins:

• TCK → TCK
• TDI → TDI
• TDO → TDO
• TMS → TMS
• GND → GND
• TRST (optional) → nTRST on the MCU                                                                                                                                                                                                  Check if  the OpenOCD version you installed supports your FTDI module (e.g., FT2232H or FT4232H).If you are interested in OpenOCD on Raspberry Pi, you      can see here:  www.pcbway.com/.../OpenOCD_on_Raspberry_Pi__Better_with_SWD_on_SPI.html
  
  

Thanks for your information. Now I'm able to connect FTDI successfully with OpenOCD. But to connect it to my EVAL board it is giving me this problem.
